1. 5-8 Graphing Absolute Value Functions

2. Absolute Value Function: has a V-shaped graph that opens up or down
Absolute Value Function: has a V-shaped graph that opens up or down. 𝑦= 𝑥 Translation: the shift of a graph horizontally, vertically, or both. The result is a graph of the same size and shape, but in a different position

3. Problem 1: Describing Translations

5. 𝑦= 𝑥 +𝑘 𝑦= 𝑥 −𝑘 Translates y= x up k units (If k is a positive number)
Translates y= x down k units (If k is a negative number)

6. Problem 2: Graphing a Vertical Translation

9. Problem 3: Graphing a Horizontal Translation

11. Piecewise Function: a function that has different rules for different parts of its domain. Step Function: is a function that pairs every number in an interval with a single value. They look like a stair case (Each piece of the graph is a horizontal segment that is missing its right endpoint, indicated by an open circle

12. Problem 4: Graphing a Step Function
A school will charter buses so that the student body can attend a football game. Each bus holds a maximum of 60 students. Make a graph that models the relationship between the number of students x that go to the game by bus and the number of buses y that are needed.
